LoTherme-408

A low heat input electrode for SS308L deposits.
CHARACTERSTICS
  • Characteristics :Quiet and stable arc, which is easy to strike and re-strike.
  • Low carbon deposits increase the resistance to intergranular corrosion.
  • On horizontal fillet welds, produce more of spray arc and a finer rippled weld bead. The weld metal is of radiographic quality.
  • Electrode can be used in horizontal, vertical up and overhead positions.
  • Detachability of slag is very easy.
APPLICATIONS

LoTherme-408 is ideally suited for repair & joining of stabilized as well as un-stabilized 18Cr - 8Ni stainless steels of normal as well as extra low carbon versions. It can also used for welding cast steels of matching composition.

Typical Mechanical Properties of All Weld Metal:

ULTIMATE TENSILE STRENGTH : 59 kgf/mm2

ELONGATION (L=4d) : 38 %


Welding Technique :

Re-dry the electrodes at 300-350 C for one hour. Clean the weld area free of rust, oil, grease, paint, or any other surface contamination. To ensure minimal heat input, use short arc and stringer bead technique.

Current Conditions : DC (+) / AC
